To-alllwhom it may eminem:

euer-avaa csp Be it known that L -Gosmvn 'A acitizen of the United Statesv of America, and a resident of Auburn, county' of Sanganien,` and State oflllinois, have invented certain new and useful Im rovements in Electrical Connectors,'of which the' followin' is a specification'.I

y invention relates to' improvements in electrical connectors, and/has for its object the provision of means for. most readily cuit,- under' the after detailed. n

establishing and breakingan electrical circonditions' of use herein- More particularly, my invention 'is pri- `maril designedfor use in connection with adapted for employment when the train is iexib e conductors 4"for mining motors enterin aroomor passage of the mine linto which t e trolley conductor does not extend. It is frequently found necessary in practice to employ a flexible conductor in Eon nection with' reel-mechanism for conveying ycurrent to the motor when enterin rooms or passages littleused, those new yconstrueted 'or where the rails have' not `vbeen bonded or are formed of wooden stringere.

The common practice has 'to hook.

"one terminal of a 'flexible conductor `over .30`. contact With the bonded rail to establish the trolley, and adjustthe other terminal vcircuit with the motor'jas it -proceeds beyond the trolley conductor. This involves not a i vlittle delay, since'the motor must be stopped until` connection is made or broken.

Accordingly," I have devised means, useful under other conditions as Well, whereby the l end of the 'flexible conductor may be instantly connectedwith a suitable terminal socket, and will be automatically. disconnected therefrom upon the return ofthe motor. ,This improvement contemplates the use of a socket suitably construct-ed toadmit of yinnnediate* connection andf' automatic 45 each roonror passage, Vivhe'reinit is desired that'rthe `motor shall proceed beyond' the disconnection, positioned at theentrance of v`trolley f'thirdfrailfconducton Atthe end fof tlieffleiibleconductor "normally" Wound upon reel, fbut adapted*automatically` to be paid out or rewound, is asuitable -c'onef-anfassen 1 inumana-inmune, imf. mn1w.sa1,1s a

The pin-socket may .be longitudinally slit for insuring better engagement with the co-acting pin Z2. A

Assuming that the terminal connector is attached at the end of a flexible two-strand by inserting said terminal `connector in the manner shown in Figs. l'lto 3.

Some of the utilities ofmy invention may now be briefly referred to; principal of which is the employment thereof in mines.

It will readily be seen, however, that the.

device-is one well adapted for'use in connection with any electrical appliance, wherein strain upon the conductor is to be resisted in one direction', and the connection is to be automatically broken, and the parts separated, upon imparting any considerable strain from the opposite direction, or where a prompt release of the parts alone is de- 2-5 sired. A

. Accordingly, the device would be ladapted for use as awall socket and terminal con- "nector, when constructed of relatively small dimensions in making the connection for portable lamps, fan-motors and the like.

When employed as a temporary connector for mine-motors, it will be seen that the terminal connector may be immediately slipped into the flanged metal socket-member, so that the pins or extensions f are brought down into engagement with the edges of the ears c, while thenose fis' yieldingly held between the inner faces of said ears. In this position, the pin-socket 40 slips over its co-acting contact pin, and the terminal connector is retained in place against any normal strain imparted from al 'direction to the right of the socket; all as Will be readily appreciated by making reference to the drawing and particularly to Fig's. 2'and 3. The device, of course, will be constructed of suiiiciently large size to withstand the somewhathard usage referred .to, and the connections of the positive and 5o negative conductors will be' continuously maintained until the respective parts are separated.

When the motor returns from its excursion into any given room or passage, upon passing the connection-socket the terminal connector will first be separated from its contact pin; turning upon the projections f as a pivot (indicated by the arrow, Fig. 2),

,which projections or pins will be immediately. released from the flanged guides c,

since the strain will now be ina direction vfrom the left of the .connection-socket. .Ac-

cordingl it is necessary only for the motor to slow own in order to enable an attendant to slip they terminal connector into place within the socket, `and this part is automatically released when the motor Ireturns and passes the particular connectionsocket in use.l 4 In this way,'-not a little time is saved,

and the circuitv is com leted to the motor wherever it may procee withinthe mine.v
